Kerbstones can be installed by hand, but more often they are machine-made and delivered to the job site ready to be placed. The process of installing curbstones is typically not difficult, but it does require some care and precision. First, the area where the curbstone will be placed must be excavated and levelled. Next, a bed of sand or gravel is often placed to help support the curbstone. Finally, the curbstone is set in place and secured with mortar or another type of adhesive.
